I have grown up and lived in English and French-speaking countries and have attended international schools. As a result I’m fluent in English and French and have a basic grasp of the other Latin/Romantic languages (Spanish, Italian and Portuguese) but also of German and Dutch. It sounds ridiculous to say this but due to being around international people all my life I speak very slowly and clearly when speaking with non-native English speakers. I’m easy to understand.
For the convenience of international clients I accept Sterling, Euros, Dollars and Bitcoin.
